In the title compound, C 17H 13BrClNO, the dihedral angle between the naphthol ring system and the chloro-benzene ring is 76.59 (11)°. This twisted conformation is supported by an intra-molecular O - H⋯N hydrogen bond. In the crystal, [100] chains arise, with adjacent mol-ecules linked by an N - H⋯O hydrogen bond, a C - H⋯π inter-action and an aromatic π-π stacking contact [centroid-to-centroid separation = 3.783 (2) Å]. Weak C - H⋯O inter-actions also occur.
